Out of disc space

Please help me understand why I’m suddenly out of disc space even though I haven’t added any data. My disc usage suddenly went from 8mb to 148, putting me above the limit for my plan and I’m being prompted to upgrade. Only thing I did was add a new screen to experiment with the app builder. I have deleted the new screen but there’s still no change in disc space usage. What’s going on?

Sent an email to that address about 2 days ago. Status still the same and I haven’t heard from anyone. Really frustrating
